Help - a question on log file - comp.os.linux.misc

Hi, I'm using RH Linux 9.0 and found an issue with /var/log/messages. It seems the content of /var/log/messages stays the same and won't be updated any more even after a reboot. dmesg still shows log update. How can I "reset" /var/log/messages and let it update? Thanks, T.

The 'messages' in /var/log/messages are normally appended at the end of the file and /var/log/messages does not get erased and re-created like /var/log/dmesg at boot. As root type; rm /var/log/messages service syslog restart cat /var/log/messages (expected output, modified for word wrap) Jul 19 16:22:29 Laptop1700 syslogd 1.4.1: restart.

After a reboot, I still can not find "/var/log/messages" and "/var/log/messages." is still empty. What I missed?

After a reboot, I still can not find "/var/log/messages". What I missed?

Very strange! I thought I had already answered this? Do you have multiple posts? Check your /etc/syslog.conf file, "man syslog.conf" for details. This is the file that tells the system where to log what. -- Juhan Leemet Logicognosis, Inc.

Somehow, syslog.conf got modified. After restoring it, /var/log/messages logs all messages. Thanks, T. -- > -- > Juhan Leemet > Logicognosis, Inc. >
